We will strictly test and check our products, such as steel surface quality should be smooth, not permit folding, cracks, delamination, take the existence of welding defects. Allowed no more than pipe wall thickness of the surface of a negative bias is zoned Road, scratches, weld dislocation, burns and other minor flaw. Allow welds and inner wall thickening seam welding bars there.

 

welding steel pipe increasing number of varieties and specifications, and in a growing number of areas instead of non-Steel Pipe, than the seamless steel pipe welded steel pipe and low cost, high production efficiency.
